Definitions
- the invention relates to a rubber-elastic spring with hydraulic damping, which identifies an annular rubber-elastic spring element, that is a spring element made of an elastomer such as rubber or a plastic with rubber-elastic behavior after e.g. DIN 7724.
- the associated rubber-elastic spring element is in each case an upper and a lower ring-shaped, usually vulcanized
- the rubber-elastic spring further includes one of a
- Working chamber and a compensation chamber existing hydraulic chamber which is surrounded by the annular spring element and / or the annular Rantücken so that changes in compression the volume of filled with a damping medium working chamber, and provided with at least one connecting channel between the working chamber and compensation chamber separating element.
- Throttle holes are arranged. Upon deflection of the hydraulic spring shown there, the working chamber is reduced, whereby the liquid in the working chamber through the Throttle holes is pressed and damped by the resulting dissipation.
- the formation of the throttle bore disadvantageously produces no appreciable damping. With such a throttle results in a rather low attenuation, which also begins only at high frequencies.
- the EP 1 346 166 Bl discloses a hydraulic spring with damper, which has a sufficient damping effect at very different loads and frequencies due to the relatively long damping channels in the separating element. Disadvantageously, the height here, however, is relatively large.
- the task was a hydrofeather, i. to provide a rubber-elastic spring with hydraulic damping, which provides a sufficient and adjustable damping in different frequency and load ranges and still has only the smallest possible structural dimensions.
- the separating element is at least one disc with a in the
- Disc level extending connecting channel formed and arranged within the vertical heights of the spring element and a connecting piece, i. within the height extent of these parts in spring axis, or axis of the spring force effect.
- the separating element is arranged within the connecting piece so that the
- the rubber-elastic spring element is designed as a hollow cone open at the top, which has a vulcanized on its inner cone upper and a vulcanized on its outer cone bottom
- Connecting piece is connected on the one hand to the sprung body and on the other hand to the unsprung mass, and in which the separating element within the upper
- Connecting piece is arranged so that the compensation chamber between the separating element and the end of the upper connecting piece is formed.
- the conical shape not only optimizes the spring properties, it also provides a larger - if concentric arrangement - within the components with the same load-bearing capacity of the spring
- a further advantageous embodiment consists in that the separating element consists of a plurality of disks arranged one above the other, the channels of which are connected in a communicating manner.
- a further advantageous embodiment consists in that the length of the connecting channel formed by a plurality of disks can be changed by rotating the disks. This allows the rubber-elastic spring element either after the
- connection channels located in the discs are milled on one side. This makes it possible to produce the corresponding channels in a particularly simple and cost-effective manner. The respective coverage of the channels is then at least partially through the adjoining adjacent disc or the connector.
- compensation space is limited by a cover at the end of the connection piece.
- connection piece is possible, the liquid used for damping is particularly well protected against the ingress of foreign bodies or moisture, the same applies to a further advantageous embodiment, which consists in that the compensation chamber is limited by a disposed within the connector membrane. But with such and additionally pronounced elastic membrane can also be a
- Spring element as a laminated spring, that is designed as a rubber-metal element.
- the load capacity of the spring increases, so that deflection, change in the volume of the working space and damping can be designed for particularly high loads, which is particularly at.
- Rail vehicles is required, which must catch between unladen and laden state load differences of about 1: 5.
- the properties of the elastic rubber-elastic spring according to the invention in terms of damping and the size can be accordingly in a chassis for a
- Fig. 1 shows a rubber-elastic spring according to the invention
- Fig. 2 shows another embodiment of a rubber elastic according to the invention
- Fig. 3 shows another embodiment of a rubber elastic according to the invention
- Fig. 1 shows a rubber-elastic spring 1 with hydraulic damping for a chassis of a rail vehicle, comprising an annular rubber-elastic spring element 2, which in each case via an upper and a lower ring-shaped connecting piece 3 and 4 with on the one hand the sprung body and on the other hand with the unsprung mass connected is. Sprung body and unsprung mass, so the body and chassis of the rail vehicle are not shown here.
- the rubber-elastic spring 1 furthermore has a hydraulic chamber consisting of a working chamber 5 and a compensation chamber 6, which is surrounded by the annular spring element 2 and the annular connection pieces 3 and 4 so that the volume of the working chamber 5 filled with hydraulic oil as the damping medium during spring deflection is 5 changed. Also provided with at least one connecting channel 7 between the working chamber 5 and the compensation chamber 6 separating element 8 is provided, which is formed as at least one disc 9 with a extending in the disc plane connecting channel 7.
- the upper connecting piece 3 in this case has a corresponding bore 10, through which the hydraulic oil can enter into the connecting channel 7.
- the upper connector 3 is thus formed as a compact cup-shaped body and thus according to manufacture easily and accurately.
- the separating element 8 is disposed within the vertical heights of the spring element 2 and the connecting piece 3, in such a way that the compensation chamber 6 is formed between the separating element 8 and the end facing away from the latter end 11 of the connecting piece 3.
- the rubber-elastic spring element 2 is constructed as a laminated spring, that is designed as a rubber-metal element and in the form of an upwardly open hollow cone.
- the rubber-elastic spring element 2 is on the vulcanized on its inner cone upper connector 3 and on the vulcanized on its outer cone lower connector 4 with on the one hand the sprung body and on the other hand with the
- the connecting piece 3, which has the separating element 8, is provided with a plurality of a seat or a recess for receiving one or more panes 9, 14 and 15, which individually or jointly form the separating element.
- Fig. 1 shows a rubber-elastic spring 1, which is provided only with a disc 9, while Fig. 2 is a rubber-elastic spring 21, which is provided with three discs 9, 14 and 15.
- the separating element 16 consisting of three disks 9, 14 and 15 is constructed so that the channels of the disks 9, 14 and 15 are communicatively connected with each other and thus provide a long connection channel 17.
- the three discs 9, 14 and 15 can be rotated against each other here, so that the length of the connection channel 17 formed by three discs is variable.
- the connecting channels located here in the discs 9, 14 and 15 are not milled on one side, but arranged in so-called “built” discs, which are constructed by corresponding annular body and cover or intermediate discs and fixed by a central screw 18 in the connector 3.
- Die single disc 9 in Fig. 1 is also a "built” disc, which by a cover plate 19 in
- the compensation chamber is in those shown in the Fig.1 and Fig. 2
- Embodiments is open at the top, while the working chamber 5 is closed by a cover 20 at the end of the fitting 4.
- FIG. 3 shows a further embodiment of a rubber-elastic spring 22 with a separating element consisting of three disks, in which the compensation chamber 6 is bounded by a membrane 23 arranged inside the connecting piece and closed by a further cover 24.
- the spring 22 is thus well protected as a compact all-round closed element against the ingress of foreign bodies or moisture and can not be damaged during transport or installation.
